1:30 CFD leverage: national rules and account classification

On the first of August 2018 the ESMA retail CFD measures introduced a maximum opening leverage of 1:30 for CFDs referencing major currency pairs within their scope, almost overnight. The decision came from ESMA, the European Securities and Markets Authority, after data gathered by national supervisory authorities showed that somewhere between 74 and 89 percent of retail CFD accounts were losing money. This was never a broker's marketing choice or a single national whim — it was a shared European safety brake. In this article I explain where the number 1:30 actually came from, how the cap works in practice, and what it means for an account held under a national regulator such as the Polish KNF.

What did ESMA actually change on the first of August 2018?

Formally this was ESMA Decision (EU) 2018/796 on temporary product intervention measures relating to contracts for difference (CFDs). It applied from 1 August 2018 for three months and was successively renewed. The final renewal expired at the end of 31 July 2019. Protection then passed to decisions taken by national supervisors. In Poland the legal basis is the KNF decision of 1 August 2019, which alongside the retail cap also provides for an "experienced client" category — leverage of up to 1:100 on selected instruments, once conditions on trading history and knowledge of the instrument are met. That is not the same thing as professional-client status. The details therefore differ from one country to another, and it is a mistake to assume the rules read identically everywhere.

Leverage was the loudest part of the package, but it was not the only limit. The ESMA cap is tiered by asset class — the more volatile the instrument, the lower the leverage allowed.

On top of that came three protections that work independently of leverage. The first is mandatory negative-balance protection — aggregate liability for CFDs linked to the account is limited to the funds in that CFD trading account, including after a violent gap. The second is a compulsory margin-close-out when account funds and net unrealised profits fall below 50 percent of the total initial margin protection requirement for the open CFDs. The third is a standardised risk warning in which the broker must publish its own current percentage of losing accounts. Together with a ban on deposit bonuses this forms a coherent package — it was never only about leverage, but about the entire shape of retail trading conditions.

Why exactly 1:30, and not 1:50 or 1:10?

ESMA described the opening limits as varying with the volatility of the underlying asset and introduced them alongside account-level safeguards. The 30:1 tier belonged to its defined major-currency category; it was not a finding that every position at that ratio was safe. A regulatory tier therefore answers which minimum collateral rule applies, while the position’s size and price movement determine its price result.

A cap of 1:30 means initial margin of roughly 3.33 percent of notional value. Its purpose is to limit the risk that comes with high leverage, not to make anyone profitable. Even at 1:1 a CFD is not the same thing as buying the currency outright — it is still a contract with the broker, with its own settlement and its own costs. And even a 1:30 cap leaves room for a painful loss if you use a substantial part of the exposure available to you. The real risk depends on your volume, on how far the price moves and on the funds sitting in the account.

How does the ESMA cap compare with other markets?

Leverage limits are not global — they are regional, and any trader reading English-language forums should keep that in mind. Rules that look like a "market standard" in fact apply only within a given jurisdiction.

The FCA’s current margin rules cover specified UK retail speculative investments; its PS19/18 from 2019 explains their introduction. Australia’s CFD order applied from 29 March 2021 and was extended to 23 May 2027. Its major-currency definition includes AUD, unlike the six-currency group in the Polish decision. Japan’s 4% OTC FX requirement concerns individuals, while corporate and exchange-traded models differ. US covered off-exchange retail forex has 2% and 5% security-deposit floors; the applicable association or provider may require more. An advert promising “1:500 leverage, regulated broker” identifies none of these scopes by itself. Match the contracting entity, authorised service, product and client classification to the applicable rules.

What does the 1:30 cap mean in practice for your deposit?

The most tangible consequence is that the same position size now requires much more margin. The margin requirement is simply the inverse of leverage — at 1:30 it works out to 3.33 percent of contract value. The gap between the ESMA cap and an offshore offer is enormous, which is why low leverage is so often mistaken for a drawback.

At an exact hypothetical 1:30 rate, EUR100,000 / 30 is about EUR3,333.33 before account-currency conversion. A regulatory minimum does not guarantee that a provider offers that rate: use the actual symbol and account margin requirement, which may be higher. Scale the calculation to your chosen volume. See how leverage differs from margin.

A leverage cap limits the exposure you can open for a given margin balance, but it does not determine your loss per trade. Combine sizing with the chosen risk budget and allow for execution uncertainty. Negative-balance protection is a separate safeguard under the applicable retail CFD regime and operates at account level. The low initial margin at 1:500 can tempt a beginner to take excessive exposure; understand the high-leverage trap before placing an order.

Professional-client status — is giving up protection worth it?

The historical ESMA intervention concerned retail CFDs. Under MiFID II, professional classification on request requires a firm’s assessment and the specified procedure. At least two of the listed criteria must be met: significant transactions on the relevant market at an average of ten per quarter over the previous four quarters; a portfolio including cash deposits and financial instruments above EUR 500,000; or at least one year in a financial-sector role requiring relevant knowledge. Meeting those criteria alone does not guarantee reclassification or a 1:500 offer. The firm must provide a written warning, and the client must acknowledge the consequences separately. Compare retail, experienced and professional client classifications before requesting a change.

Changing to professional classification changes the statutory retail CFD safeguards. A provider may offer some protections voluntarily, while compensation eligibility requires a separate check under the relevant scheme. Confirm the protections and obligations in the actual agreement before requesting the change; classification is not evidence of trading skill or future gains.

What to do after you close this page

1. Check your actual margin requirement. Read the correct account and symbol specification, including the calculation mode, contract size, rate and account-currency conversion. Within the Polish KNF decision’s scope, the minimum for a retail client without experienced status is 3.33% for combinations of its six listed currencies and 5% for other FX pairs; a provider may require more. Do not infer the offered rate from a market “major” label.
2. Verify your broker's licence in the regulator's register. Open your national regulator's website, find its register of authorised investment firms, and type in the broker's name. If it is not there, check the public-warning list as well — a warning list is supplementary, and registration alone does not guarantee protection from losses or fraud. The regulations section walks through how to read these registers.
3. Work out margin for your typical position. Multiply the contract notional by the actual required margin rate, then apply the specification’s conversion and calculation rules. Dividing by 30 is appropriate only when the model explicitly assumes exact 1:30 leverage.
4. Think hard about your client status before clicking "professional". If a broker offers higher leverage in exchange for reclassification, read carefully which protections you are giving up, and weigh that against the underlying concept of leverage and what it really does to your downside.
